Explanatory Notes

You can search on any combination of these fields. If you enter information
into the Registration, Serial Number or Aircraft Type/Name fields, you must
enter at least two characters. If you enter information into the Registered
Owner or ICAO 24 bit aircraft address fields, you must enter at least three
characters.

Please note that the "Registration" search will return both registered and
de-registered aircraft. The other search fields will only return currently
registered aircraft unless the "View de-registered aircraft" box is checked in
which case only the de-registered aircraft will be returned. The "Registration"
search will retrieve all records that begin with
the phrase entered whereas the "Serial Number", "Aircraft Type/Name", "Owner"
and "ICAO 24 bit aircraft address (hex)" will return all records containing
that phrase. For instance, searching "Owner" with smith
might return Paul Smith, Smith
and Co and Peter Smithson.

You can also use * as a wildcard. For instance,
searching "Aircraft Type/Name" with BEECH 200 will
only return BEECH 200, however searching on
BEECH*200 will return BEECH 200 and
BEECH B200. Data can also be entered in any combination of the
search fields to further refine your search.

The "Aircraft type/name" search field simultaneously searches on
the manufacturer, full type name, popular name and generic name of
the aircraft. If you are unsure of the designation of an aircraft put in the
simplest description of the aircraft (generic name),
eg PA34 for a Piper PA-34-200T, a single line listing of all examples will
appear. From the information displayed you will be able to refine your search
to reduce the number of records retrieved.

Alternatively enter the popular name for the
aircraft, eg Citation for a Cessna 500, a single line listing of all examples
will appear. From the information displayed you will be able to refine your
search to reduce the number of records retrieved.

The "ICAO 24 bit aircraft address (hex)" searches on the hexadecimal version of
the ICAO 24 bit aircraft address. This address is used for various purposes
including Mode S transponders and emergency locator transmitter equipment.
